Pesticides, PCB and PAH

Pesticides in Food or Feed

Pesticides are chemical substances, which are used to prevent damage on e.g. arables caused by insects, fungi or nematodes. These are used by farmers and growers in conventional agriculture and horticulture. Consequently, the amount of pesticide residues on food and animal feed are regulated by law in order to protect the consumer and livestock or pets from any possible damage.

Unfortunately in both food and feed, maximum permissible residue limits are found to be regularly exceeded.

This may be due to lack of application of the rules of "Good Agricultural Praxis" for pesticide application, the usage of banned pesticides, or the deliberate evasion of rules. In order to guarantee to the consumer safe and healthy food, comprehensive and strict controls are essential.  

 

 

For this area of application, especially when looking at compliance with the revised DFG S19  (L 00.00-34), the AOAC methods 984.21, EN 12393 or EN 1528 and other analytical methods, LCTech offers a comprehensive product range. In particular their FREESTYLE system, with its modular design, caters for all aspects of residue analysis at any required level of automation.

FREESTYLE system equipped with GPC and EVAporation module and a selection of racks for the automated sample preparation of pesticides

Automated Sample Preparation with FREESTYLE

 

Recommended configuration

  • for  clean-up with GPC column: FREESTYLE with GPC module and corresponding racks for sample processing via GPC (Gel permeation chromatography).
  • for evaporation to a defined endvolume and solvent exchange: additional EVAporation module (can be updated).

We are happy to assist you with the configuration of an LCTech FREESTYLE system - exactly tailored to your applications and your need for automatisation.
